Nice hotel, great price, heart of Bayswater
I have been staying at the London House on my visits to London for three years now. First, it's great location in almost every way. Two Tube stops, different lines, within a five-minute walk. The neighborhood has just about everything with a short walk -- restaurants and pubs galore, coffee shops, markets, drugs store, a mall, etc. You'll never be bored in the area and, if you are, you're a Tube stop or three away from something interesting.
As for the hotel itself, I am amazed that something so satisfactory in almost every way is so damn (relatively) inexpensive. The first year, I found the place for just one night. Stayed in a very small room (barely enough room for the single bed). But it was well priced and quite comfy. The next year, I stayed for a week in a double room. Again, the price was terrific and my stay was fine in every way. This year, my family and I booked a family room. It has one double bed and two singles. The price was great (about $200 a night, which in central London is a steal). Despite the fact that four adults (we have 17-year-old twins) occupied the room, we never really felt cramped. The room wasn't enormous, but it was relatively spacious. The bathroom was larger than the usual bathrooms at the London House.
The only real deficit is the lack of a bar or restaurant. But, as I say, there are plenty around the corner. The breakfast is continental and, at 7 pounds, far to expensive for what they served. I'd recommend skipping that.
